RESUMO

We study the behaviour of solutions for the nonlinear heat equation with Dirichlet boundary conditions on a bounded subset of RN. We introduce the notion of weak solutions for this type of problem, and study the relation between such solutions and weak solutions for the associated stationary elliptic problem. Basic notions on Lebesgue spaces, Sobolev spaces, semigroup theory are treated, as well as the comparison principle for parabolic problems both in classical and weak senses
